First. The Brain is the Organ of the Mind. This is assumed, because too universally admitted to require proof.

Secondly. Is the brain, then, a SINGLE organ, or is it a bundle of organs? Does the WHOLE brain think, remember, love, hate, etc.; or does one portion reason, another worship, another love money, etc.? This is the determining point. To decide it affirmatively, establishes Phrenology; negatively, overthrows it. It is proved by the following facts.

The exercise of different Functions simultaneously.—We can walk, think, talk, remember, love, and many other things all TOGETHER, —the mind being, in this respect, like a stringed instrument, with several strings vibrating at a time, instead of like a flute which stops the preceding sound when it commences succeeding ones; whereas, if it were a single organ, it must stop thinking the instant it began to talk, could not love a friend and express that love at the same time, and could do but one thing at once.

Monomania.—Since mental derangement is caused only by cerebral disorder, if the brain were a single organ, the WHOLE mind must be sane or insane together; whereas most insane persons are deranged only on one or two points, a conclusive proof of the plurality of the brain and mental faculties.

Diversity of Talent, or the fact that some are remarkable for sense, but poor in memory, or the reverse; some forgetting names, but remembering faces; some great mechanics, but poor speakers, or the reverse; others splendid natural singers, but no mechanics, etc., etc., conducts us to a similar conclusion.

Injuries of the Brain furnish still more demonstrative proof. If Phrenology be true, to wound and inflame Tune, for example, would create a singing disposition; Veneration, a praying desire; Cautiousness, groundless fears; and so of all the other organs. And thus it is. Nor can this class of facts be evaded. They abound in all phrenological works, especially periodicals, and drive and clench the nail of proof.

Comparative Phrenology, or the perfect coincidence existing between the developments and characters of animals, constitutes the highest proof of all. Since man and brute are fashioned upon one great model, those same great optical laws governing the vision of both, that same principle of muscular contraction which enables the eagle to soar aloft beyond our vision, and the whale to furrow and foam the vasty deep, and enabling man to walk forth in the conscious pride of his strength, and thus of all their other common functions; of course, if man is created in accordance with phrenological laws, brutes must also be; and the reverse. If, then, this science is true of either, it must be true of both; must pervade all forms of organization. What, then, are the facts?

Phrenology locates the animal propensities at the SIDES of the head, between and around the ears; the social affections in its BACK and lower portion; the aspiring faculties in its CROWN; the moral on its TOP; and the intellectual on the FOREHEAD; the perceptives, which, related to matter, OVER THE EYES; and the reflectives in the UPPER part of the forehead. (See cut No. 14.)

Now since brutes possess at least only weak moral and reflective faculties, they should, if Phrenology were true, have little top head, and thus it is. Not one of all the following drawings of animals, have much brain in either the reflective or moral region. Almost all their mentality consists of the ANIMAL PROPENSITIES, and nearly all their brain is BETWEEN and AROUND THEIR EARS, just where, according to Phrenology, it should be. Yet the skulls of all human beings rise high above the eyes and ears, and are long on top, that is, have intellectual and moral ORGANS, as we know they possess these mental ELEMENTS. Comparing the accompanying human skull with those of brutes, thus those of snakes, frogs, turtles, alligators, etc., slope straight back from the nose; that is, have almost no moral or intellectual organs; tigers, dogs, lions, etc., have a little more, yet how insignificant compared with man, while monkeys are between them in these organs and their faculties. Here, then, is INDUCTIVE proof of Phrenology as extensive as the whole brute creation on the one hand, contrasted with the entire human family on the other.
